Are original mix tapes always used for releases that require them (surround)? 2019-07-12 20:13:46 This seems like a question with an obvious answer, but i've never spent a lot time in a studio, so i don't want to assume. I have a lot of music in surround (dvd-a and sacds). When i catalog my music on my computer, i like to add a tag that states whether the mastering source was an original or not. Labels like Mofi and Analogue Productions get a tag of "remastered from original master tapes".For my surround discs, shouldn't i be giving them a tag of "remixed from original source tapes"? Do copies of source tapes get made and distributed like masters do, or would the originals always be used to make the remix for a surround release, provided they was of usable quality? This only apples to surround releases of non-digital material of course.Also, i note this is not a measure of quality. Even if the originals were used, my 5.1 tracks from the dvd-a of Disturbed's "Believe" still sound like someone shoved the band into a shoe box filled with cotton, stomped on it a few times and put what spilled out onto the disc. According to ffmpeg it has a DR of 9.2, so not terrible. I blame the recording not the mastering. Sad, as it's one of my favorite albums.
